This invention relates to the irrigation of field crops, forming a supply of water confined as a ditch between temporary levees thrown up along the field during the growing season, and particularly to aportable siphon by means of which the water may be taken from the ditch at any point and distributed between the rows of growing crops, without cutting the levees.

One of the objects of this invention is to provide a siphon of this generalcharacter constructed so that it is very'light, enabling the same to be easily picked up and carried about without much effort, and yet which is so strong and rigid that it may be subjected to ordinary rough treatment without damage or the likelihood of a leak developing.

A further object is to provide a gate for the siphon, so that the flow of Water therethrough may be controlled and such water allowed to issue in a quantity sufficient to thoroughly penetrate the soil, the siphon and gate being so constructed relative to each other that the gate may be readily mounted on either end of the siphon as the position of the latter relative to the ditch may necessitate, or said gate may be removed A and omitted if its use is not desired at any time.

A further object of the invention is to provide a simple and inexpensive device an'dyet one which will be exceedingly effective for the purpose for which it is designed.

These objects we accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawing similar characters of reference indicate corresponding parts in the several views. I

Figure 1 is a side elevation of the siphon and gateunit as disposed in place and as in operation. 9 i a Figure 2 is a fragmentary enlarged sectional elevation of the siphon and gate. 1

Figure 3 is a fragmentary top the unit.

Figure 4 is a cross section on theline 3--3 of Fig. 2, looking toward the gate. 3

Referring now more particularlyto the characters of reference on the drawing, the siphon plan view of I is built up of three straight sections of thin galvanized or similar pipe or tubing, the top central leg I being relatively short, while the legs fieldlevee 3 thrown up between the water supply and the crop growing area.

The siphon legs. are cut on the bias at their I adjacent ends and abut against each other, being connected'and sealed against leakage by heavy continuous weld beads 4 thereabout. By

means of. this feature the siph'onis very rigid at the joints, giving great strength and freedom' distortion, but provide a smooth surface for engagement with the hand of the operator, who

\ when starting the siphon-closes one end of the same with the palm of the hand. A very light siphon is therefore provided, which at the same time is verystrong and substantially proof against collapse or leakage by reason of the reinforcing end rings and the heavy weld beads at the joints. Also by reason of the equal length of the legs 2 either end of the siphon may be placed in the ditch.

In connection with the above described siphon I have provided a removable gatewhereby the flow through the siphon may be controlled. This gate comprises a'flat thin metal plate 1, longer;

than the diameter of the siphon, and preferably cut upwards from the bottom somewhat as at 8 and provided on top with an outwardly bent fin-' ger tab 9. .Down the sides the gateis bent over inthe direction opposite the tab 9, to form parallel open ended semi-circular channels or grooves 10 of substantially the same size as the outermost portions of the siphon beads B so that said grooves may engage either bead with ing friction fit,

Either head at a time thus not only. serves to reinforce the siphon but. also serves as a mounting and guide means for thegate, enabling the latter to be slid up and down and retained in any position on the siphon, or to be removed entirely if an unobstructed flow is desired. The

- channels IE! on the gate, besides serving to su'pport the same from'the siphon, stiffen the gate vertically and allow the same to .be made of thinner metal than would otherwise be the case; The cutting away of the gate at the bottom en-- ables a relatively wide open position to be maintained while still retaining the channels l9 engaged with the circular head 6.

a slid- From the foregoing description it will be readily seen that we have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention. as defined by the appended claims.

Having thus described our invention, what we claim as new and useful and desire to secure by Letters Patent isi V 1. A portable irrigation siphon comprising a central leg and end legs of equal length and anprojecting identical flange elements on both legs at their outer end, and a gate to 'removably and slidably engage the elements of either leg at a time.

2. A portable irrigation siphon comprising a central leg and end legs diverging therefrom, outwardly projecting continuous reinforcing beads about the end legs at their outer end, the beads of both: legs being of identical size, a single gate and side channels on the gate to slidably and removably engage either head at a time.

3. A portable irrigation siphon comprising a central leg and end legs diverging therefrom, an outwardly projecting continuous reinforcing bead secured on one end leg at its outer end, a gate,

and parallel facing channels along opposed edges opposed points. 15 gularity diverging therefrom, opposed outwardly.v A e I of the gate slidably embracing said bead at HARRY V. MORRIS. LOWELL H. MORRIS. JAMES E. MORRIS.
